The transfer of heat to the air is bigger if the surrounding air has a lower temperature.

There's a thin layer of hot air around your food. You're blowing that layer away; what's left is a hot meal with cold air around it. The cold air forms a new thin layer of warm air, repeat.

you blow the heat particles of of the food

>>2580100
nope

you are blowing cold particle onto the food

specifically anti-thermions

>>2580100

>heat particles
get the fuck out.

If you put a bunch of fans in a room, will it lower the temperature of the room?

>>2580128
no

but it will speed up heat transfer away from the hot things (people) to the cooler things (the air)

it makes hot water evaporate, thus cooling the food

>>2580109
In reality though this is not what happens. We know the temperature of the food dercreases in a fashion which is not proportional to the amount of cold particles. Therefore there must by hypothetical 'dark' particles which also take away warmth. These particles are virtual though, so we can't directly observe them. Supposedly they're also what causes your balls to feel cold, even though you're wearing warm underpants.

lol, well played....
(if that is really you, and if you really were trolling)

>>2580217
it wasn't me but it was an obvious troll

>>2580230
aaaaahhh!!!
well fuck you then, you dont get the credit for it, and you cant prove it was a troll.

Its convective cooling. Let's just say theoretically you leave some hot food just sitting there. Let's say in one second 100 air molecules interact with the food and the food loses some heat to the molecules due to conductive heat loss. Now if you blow on the food you are moving the air molecules over the food, so instead of maybe 100 you get a thousand molecules interacting with the food taking its heat.

With fans its the same thing, they only FEEL cool, the air they are blowing is the same temperature as the air if it wasn't being blown.

now ur mad too

>>2580239
touché

lol, i was close enough.
